BACKGROUND ART

A typical electronic cigarette includes an atomizing device and a battery assembly threadedly coupled to the atomizing device. The atomizing device includes a screw sleeve at one end, a tubular electrode arranged in the screw sleeve, and an insulator sandwiched between the screw sleeve and the tubular electrode.

DETAILED DESCRIPTION

Embodiments of the present disclosure will now be described in detail below and with references to the drawings.
Referring to FIGS. 1-2, an atomizing device 1 for an electronic cigarette is shown. The atomizing device 1 is configured (i.e., structured and arranged) for atomizing tobacco liquid to form aerosol. The atomizing device 1 includes an atomizing sleeve 11, a liquid chamber 12 in the atomizing sleeve 11, and an atomizing assembly 10. The atomizing assembly 10 includes a liquid conducting component 13 and a heating wire 14 wound around the liquid conducting component 13. The liquid conducting component 13 is adapted for absorbing the tobacco liquid in the liquid chamber 12, so that the heating wire 14 heats the tobacco liquid. The atomizing device 1 further includes a first connector 15 at one end. The first connector 15 is integrally formed, and includes an insulated body 151, an inner electrode 152, and an outer electrode 153. The insulated body 151, the inner electrode 152, and the outer electrode 153 are coaxially arranged. The inner electrode 152 and the outer electrode 153 are connected with two opposite ends of the heating wire 14, respectively.
Also referring to FIG. 3, the inner electrode 152 includes a first end 1521 and a second end 1522. The first end 1521 is connected with one end of the heating wire 14. The second end 1522 includes a clamping portion. The clamping portion 1527 includes a plurality of clamping hands 1523 for clamping and fastening a to-be-clamped object (e.g., a positive electrode).
A gap 1524 is defined between every two adjacent clamping hands, so that after the first connector 15 is engaged with the to-be-clamped object, air can go into the atomizing sleeve 11 via the gap 1524. Accordingly, no additional air passage is needed, thus simplifying the structure of the atomizing device 1.
In the present embodiment, the inner electrode 152 is cylindrical. An inner diameter of the clamping portion 1527 decreases from two ends of the clamping portion 1527 to the middle of the clamping portion 1527. Thus, the clamping hands 1523 clamps the to-be-clamped object when the to-be-clamped object is inserted into the inner electrode 152. The inner electrode 152 further includes a cylindrical guiding portion 1525 at a distal end of the clamping portion 1527. An inner diameter of the guiding portion 1525 may be equal to or larger than that of the second end 1522.
The outer electrode 153 is substantially cylindrical. The insulated body 151 is made of plastic. The inner electrode 152 and the outer electrode 153 are wrapped around by the insulated body 151 to form an integral part.
In addition, the atomizing device 1 further includes an air pipe 16 coaxially arranged in the atomizing sleeve 11. The air pipe 16 may be made of glass fiber. A liquid-absorbing cotton 17 is arranged between the atomizing sleeve 11 and the air pipe 16, and is configured for absorbing the tobacco liquid. The atomizing assembly 10 is supported by the air pipe 16 in such a manner that the heating wire 14 is positioned in the air pipe 16. In this way, after the tobacco solution is absorbed by the liquid conducting component 13, and heated by the heating wire 14 to form aerosol, the aerosol flows out via the air pipe 16, and reaches a mouth of a user.
The atomizing device 1 further includes a fixing sleeve 18 arranged at one end of the atomizing sleeve 11. The fixing sleeve 18 abuts against the liquid-absorbing cotton 17. The fixing sleeve 18 is configured to engage with the first connector 15. Two ends of the heating wire 14 pass through the fixing sleeve 18, and bend to connect the inner electrode 152 and the outer electrode 153, respectively.
The atomizing device 1 further includes a mouthpiece 19 arranged at an end of the atomizing sleeve 11 away from the first connector 15. The aerosol passes through the mouthpiece 19 to reach the mouth of the user.
Referring to FIGS. 4-6, a battery assembly 2 for an electronic cigarette is shown. The battery assembly 2 includes a housing 21, a battery 22 received in the housing 21, a controller 23, and a second connector 24. The second connector 24 is integrally formed, and includes a positive electrode 241, a negative electrode 242, and an insulated medium 243. The positive electrode 241 and the negative electrode 242 are coaxially arranged. The insulated medium 243 is configured for fixing the positive electrode 241 and the negative electrode 242, and keeping them insulated from each other. The positive electrode 241 and the negative electrode 242 are connected to corresponding electrodes of the battery 22, respectively.
The positive electrode 241 and the negative electrode 242 are both cylindrical, and an annular gap is defined between the positive electrode 241 and the negative electrode 242. The annular gap is configured for receiving a tubular object.
The insulated medium 243 includes a side surface 2431, and at least one protrusion 2432 on the side surface 2431. The at least one protrusion 2432 is configured for securing the second connector 24 in the housing 21. In the present embodiment, the side surface 1431 is cylindrical, and the insulated medium 243 includes two opposite protrusions 2432 formed on the side surface 2431.
Referring to FIGS. 7-8, an electronic cigarette 100 includes the atomizing device 1 according to the first embodiment and the battery assembly 2 in accordance with the second embodiment. The first connector 15 couples with the second connector 24 so that the battery assembly 2 powers the atomizing device 1.
In detail, the clamping hands 1523 of the inner electrode 152 clamps the positive electrode 241 to form electrical connection, and the outer electrode 153 contacts with the negative electrode 242 to achieve electrical connection. In this way, the heating wire 14 is electrically connected to the battery 2.
In the present embodiment, the first connector and the second connector are each an integral part. The atomizing device engages with the battery assembly through plug connection of the first and the second connectors. Accordingly, it is easy and convenient to assemble the electronic cigarette. The production efficiency is increased, and the production cost is decreased.
It is understood that the above-described embodiments are intended to illustrate rather than limit the disclosure. Variations may be made to the embodiments and methods without departing from the spirit of the disclosure. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the disclosure.
